Abstract
The present invention provides a package for a wavelength division multiplexer (WDM). The package includes a grating comprising an alignment surface; a first sleeve comprising a mount, the mount capable of contacting the grating; and an alignment plate coupled to an outer surface of the first sleeve, where the alignment plate is capable of contacting the alignment surface of the grating. The preferred embodiment of the package also includes a second sleeve with a holding mechanism in contact with the grating. This packaging affords a quick, easy, precise and reproducible positioning and alignment of grating. Thus, the WDM is minimized in size while also reproducibly assembled with perfect alignment in a minimal amount of time.
